Discuss the Java Collections Framework with your fellow students in this discussion forum. You should tell about any interesting sources you found in your research, what you discovered, share your own ideas, and comment on what other students posted. Keep it positive and friendly, and please stick to the topic - the Java Collections Framework. The discussion Forum is not a place to discuss assignments, the course in general, or other topics. Remember -- our purpose this semester was to learn to create data structures and work with related algorithms, but in a professional environment we might be able to use existing data structures software for most projects. So you should not be wondering why this course is necessary if the data structures already exist for us to use. Learning to create the data structures software puts you a level above people who can simply use such software. This is part of the difference between a computer scientist or software engineer and a computer programmer. Your posts do not need to be long, but you should participate on at least two different day between now and when the course ends.
